The purpose of chapter 18.1.3 is to establish criteria and a process for determining when a lot of record exists for the purpose of allowing a use or development on a nonconforming lot (e.g., substandard lot that does not meet lot area, setback, or coverage regulations). The owner of lot of record shall not be denied reasonable development on a lot of record; where the underlying zone allows residential use, one single-family dwelling per lot of record is deemed reasonable use, provided applicable building codes are met. The City may also accept a legal lot determination as sufficient evidence of a hardship for in approving a variance under chapter 18.5.5.
